Impact of COVID-19 upon changes in emergency room visits with chest pain of possible cardiac origin.

We analyzed 102,033 ED visits in the COVID-19-era (March-April 2020 and 2019) and determined the proportion presenting for cardiac symptoms and their confirmed diagnoses. We observed a 16-37% decline in ED volumes overall, with a 25-50% decline in patients presenting with cardiac symptoms in March and April 2020 compared with March and April 2019. Among those presenting with cardiac symptoms, we observed a 24-43% decline in cardiac diagnoses in March and April 2020 compared with March and April 2019.
